Abstract: 12,213. Neale, J. E May 28. Impact-wheels. - Relates to means for transmitting power, and for starting, stopping, and regulating engines and motors. Fig. 2 shows the application of the invention to a motor car. A pump g is mounted on the engine shaft f<1>, and draws a supply of water or other fluid from a tank h. Fixed to the hub of each of the driving- wheels e is a wheel i of the " Pelton " type, which is enclosed in a casing i<2>, surrounding the axle and coupled to the frame of the car by a link. The wheel i, Fig. 4, is formed with a number of radial vanes, preferably of a curved form and of a fluted or hollow transverse section. A pipe j<1>, passing through the side of the casing, carries a nozzle j, adapted to direct a stream of water against the vanes. The pipes j<1> are connected by a rod j<6>, carrying a worm-wheel j<7> in engagement with a worm j<8> on a rod j<9>. The rod j<9> is coupled by bevel gearing with a rod passing through the steering-stem and provided with a hand-wheel. Upon turning this wheel, the pipes j<1> may be turned so as to adjust the angularity of the nozzles j and the point at which the streams of water strike the vanes, thereby regulating the speed. For backward driving, a fixed nozzle l carried by a pipe l<2> is arranged in connection with each wheel. Modifications of the device for adjusting the nozzle are described in which the nozzle is moved by a screw and nut, or by a rack and pinion. A drainage chamber i<6> in each casing i<2> is coupled to the tank h, or the tank may be dispensed with and the chamber coupled to the pump g. The pipes j<1>, l<2> are connected to a pipe j<4> leading to the pump, an air chamber j5 and a non-return valve being arranged in the circuit. By means of a three-way cock k, water can be cut off from the wheels i, or can be supplied to either the nozzles j or l, according to the direction in which the car is required to run. The cock k is actuated, through an arrangement of links and levers, by a hand-lever provided with a trigger adapted to engage a notched quadrant. In order to start the engines, a wheel n, Fig. 8, is secured on the shaft f<1> and enclosed in a casing n<3>. The vanes of the wheel are straight and terminate in cups n<2>. A pipe n<4> connects the water in the air chamber f with the wheel n, and is provided with a pedal-operated valve n<6>. The waste pipe n<5> from the motor is coupled to the tank h or pipe h<1>. When the valve n<6> is opened, a stream of water is directed upon the vanes and rotates the shaft f<1>. The pressure within the chamber f<5> falls and the valve f<4> is opened to supply explosive mixture &c. to the engines. In some cases, the starting-device may be used independently of the transmission gear. When the driving-axle of the motor car or the like is fitted with a differential gear, the water-wheel i is mounted loosely on the axle, and fixed to the gear box. Fig. 16 shows means for transmitting motion between the axle f<1> of a railway vehicle and the shaft e' of a dynamo e used for generating electricity for train lighting. A pump g is fixed to the shaft f<1>, and a waterwheel i to the shaft el. The waste pipe i<9> of the wheel i leads to a tank h which is coupled to the pump by a pipe h<1>. The supply pipe j<4> leading from the pump to the wheel is provided with an air chamber j<5> and is coupled to the tank h by a pipe j<4x>. The controlling-cock k is actuated by a spring-controlled arm k<1>, coupled to a Bourdon tube f<8> or equivalent, in connection with the chamber j<5>. The cock k is provided with a single passage having flared ends so arranged that all the water may be passed along the pipes j<4> or j<4x>, or part along each of these pipes. The variations in speed of the axle f<1> cause a variation in pressure in the chamber j<5>, and the cock k is actuated to regulate the water supply to the wheel i so as to keep the speed of the dynamo constant.
